. What does each line of the following code do?

fsrPin = ‘A4’; ledPin = ‘D4’;

anArduinoObj = arduino();

forceVoltage = readVoltage(anArduinoObj, fsrPin);

if forceVoltage > 4.0

writeDigitalPin(anArduinoObj, ledPin, 1);

end

Based on the Adafruit pages related to their round FSR sensor, what is the required force to read a voltage greater than 4V?

Expert Solution

fsrPin = ‘A4’; ledPin = ‘D4’; // Sets variables fsrPin and ledPin to A4 and D4 respectively

anArduinoObj = arduino(); // Recreates the last successful connection to the Arduino. If that connection

// fails, it creates a connection to the first official Arduino hardware

// connected to your host computer via USB.

// Establishes connection to the anArduinoObj object created

forceVoltage = readVoltage(anArduinoObj, fsrPin); // Reads the voltage(analog) on fsrPin into forceVoltage variable

if forceVoltage > 4.0

writeDigitalPin(anArduinoObj, ledPin, 1); // If forceVoltage measured is more than 4 then ledPin is made high. Most probably lighitng an LED.

end

I'm having trouble understanding the following code (a snippet of a code). What does it do? The whole code is about comparing efficiencies of different algorithms. def partition(list,first,last): piv = list[first] lmark = first+1 rmark = last done = False while not done: while lmark <= rmark and list[lmark]<=piv: lmark=lmark+1 while list[rmark]>=piv and rmark>=lmark: rmark=rmark-1 if rmark<lmark: done = True else: temp = list[lmark] list[lmark]=list[rmark] list[rmark]=temp temp = list[first] list[first]=list[rmark] list[rmark]=temp return rmark
